## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This Application claims the benefit of U.S. Provisional Application 61/242,607, filed Sep. 15, 2009, the disclosure of which is incorporated by reference herein in its entirety.


FIELD OF THE INVENTION
A basin or vessel is disclosed as a replacement for the integrated basin portion of a refrigerated counter. The replacement basin may be mounted to the refrigerated counter, connected to the counter's existing refrigeration system, and then used to support one or more removable product filled bins or containers.
BACKGROUND OF THE INVENTION
Refrigerated counters (including tables) have a variety of uses, but they are often used to store and display consumables at a predetermined minimum temperature. The counters, for example, are particularly popular in the fast-food industry where they are used to store and display consumables (e.g., lettuce, cheese, etc.) in open top, removable bins that are recessed within a basin(s) integrated into each counter.
Refrigerated counters may cost in excess of $50,000 each. These counters typically include at least an onboard refrigeration unit positioned under the countertop and an integrally formed or constructed countertop basin. A counter, as mentioned above, may also be outfitted with one or more open top, removable bins. The bins are designed to be recessed within the basin and may used to store and display the consumables. Counters may also be constructed to perform according to current health and safety requirements established by government and/or industry. These requirements may mandate, for example, that the open top bins positioned in the basin be maintained at a predetermined minimum temperature. NSF Standard 7, for example, established by SF International contains requirements for refrigerators and freezers used to store and/or display cold food.
The use of an integral basin in each counter allows for easy maintenance and cleaning of the basin and the counter. However, the integral construction also means that the basin cannot simply be removed from the counter. This can become particularly problematic to a user of the counter whenever changes are made to the government and/or industry health and safety requirements that the user's existing counter may not meet. The expense of purchasing a new counter, when combined with a need to comply with new requirements, means the user must choose between upgrading to a new counter or failing to comply with health and safety requirements. Either decision can translate into considerable expense, inconvenience, and possible downtime for business operations.
It would be advantageous to provide for a replacement unit for an integral basin of a refrigerated counter that would allow an otherwise functional counter (including its refrigeration system) to continue in service following a change in health and safety requirements and/or damage to the basin.
SUMMARY OF THE INVENTION
A basin or vessel is disclosed as a replacement for a basin integrally constructed into an existing refrigerated counter. The replacement basin may include a first or exterior frame that may support one or more second or interior frames, a refrigeration conduit, and optionally, a plurality of removable bins. The basin and its components may be constructed of stainless steel with the conduit being formed from copper. Although, other materials known, used or adopted by the art may also be used in the construction of the basin or its components.
In operation, the replacement basin may be installed into a refrigerated table or counter by first powering down the integral refrigeration unit of the counter and recovering any coolant present in that unit. The existing integral basin may then be separated from the existing refrigeration unit by severing the coolant lines of the unit at a predetermined location. Thereafter, the integral basin may be excised from the counter by cutting the basin away substantially along its perimeter and then lifting the basin out of the counter. After removal of the integral basin, the replacement basin may be positioned in the cutout formed by the removal of the prior basin. The replacement basin may then be further secured to the counter by welding, commercial adhesives, fasteners, or the like. Finally, the conduit lines of the replacement basin may then be connected to the coolant lines of the integral refrigeration unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to FIGS. 1-10, a basin 10 or vessel is disclosed as a replacement for a basin (not shown) integrated into a refrigerated counter (not shown). The replacement basin 10 may include a first or exterior frame 12 that may support one or more second or interior frames 14, a refrigeration conduit 16, and optionally, a plurality of removable bins 18. The frames 12, 14 may be constructed of stainless steel with the conduit 16 being formed from copper. Although, other materials known, used or adopted by the art may also be used in the construction of the basin 10 or its components.
Referring now to FIGS. 1-5, the first frame 12 may be formed as a receptacle or sink-like structure having a base or floor 20, a pair of spaced apart end walls 22, 24, a front wall 26, and a rear or back wall 28. As shown in FIG. 5, the rear wall 28 of the first frame 12 may be dimensioned longer and/or higher than the front wall 26 so that the upper edge 30, 32 of each end wall 22, 24 (see FIGS. 1 and 3) extends diagonally between the front 26 and rear 28 walls. The front wall 26 of the first frame 12 may also include a flange or lip 30 that may be used to support and/or position the basin 10 on the counter (not shown) as will be described further below.
Still referring to FIGS. 1-5, the second frame 14 may, similar to the first frame 12, be constructed to include a base or floor 32, a front wall 34, a rear wall 36, and a pair of opposed end walls 38, 40. However, as again shown in FIG. 5, the second frame 14 may be dimensioned smaller than the first 12 so that it may be recessed within the first frame 12 and have surfaces 32-40 that are spaced predetermined distances from the comparable surfaces 20-28 of the first frame 12. The second frame 14 may also be formed with (or secured to, see FIGS. 6-10 infra) a web or flange 42 that connects the frames 12, 14 along the upper edge or perimeter of the walls of the frames 12, 14.
Referring now to FIGS. 4 and 5, the refrigeration conduit 16 may be positioned in the basin 10 in the space 44 defined between the first and second frames 12, 14. The conduit 16 may engage or be positioned proximate to the surfaces 32-40 of the second frame 12 to aid in cooling those surfaces (which as will be described infra, aids in the cooling of consumables or removable bins 18 positioned in the second frame 14). Additionally, or alternatively, the conduit 16 may be positioned so that at least a portion is located above (or in a higher plain relative to the top of) the bins 18. Positioning the conduit 16 so that the conduit 16 may be above (or higher) than the tops of the bins 18 chills the air above those bins 18 and allows the temperature above and along the entire length of each bin 18 to be maintained at or below a predetermined minimum temperature. An inlet 46 and outlet 48 for the refrigeration conduit 16 may extend from the rear wall 28 of the first frame 12. However, it will be appreciated that the position of the inlet 46 and outlet 48 for the conduit 16 may be modified according to the needs of the user.
Referring now to FIG. 1, support flanges 50, 52 may be positioned along second frame. For example, as shown support flanges 50, 52 may be positioned along the front 34 and rear 36 wall of the second frame 14 and configured so that they may extend into the open receptacle or sink 53 defined by the frame 14. An intermediate support rod 54 may also be provided that extends between the end walls 38, 40 of the second frame 12. The bins 18 may then be removably positioned in the receptacle or sink 52 defined by the second frame 14, and supported by the flanges 50, 52 and rod 54. As such, it will be appreciated that consumables in the bins 18 may be refrigerated down to a predetermined temperature by operation of the conduit 16 cooling the surfaces 32-40 of the second frame 14. A predetermined amount of water (not shown) or fluid may also be provided into the receptacle or sink 52 of the second frame 14 so that the temperature is evenly distributed around several bins 18. Where a fluid is used (or intended to be used), the basin 10 may also be provided with one or more drains (not shown).
Referring now to FIGS. 1-4, a basin support flange 58 may be provided along each end wall 20, 22 of the first frame 12 of the basin 10 and used for mounting the replacement basin 10 unit to a refrigerated counter.
Referring now to FIGS. 6-10, and as best shown in FIG. 9, another embodiment of the replacement basin 10 may be constructed in which the front 26 and rear 28 walls of the first frame 12 have substantially the same dimensions. The basin 10 of this other embodiment may also include two or more inner or second frames 14, with each of these inner or second frames 14 including one or more removable bins 18. The end walls of the first frame 12 may also be configured so that the lip 30 extends around the ends of the basin 10.
Referring now to FIGS. 1-11, in operation, a replacement basin 10 may be installed into a refrigerated table (not shown) by first 100 powering down the integral refrigeration unit (not shown) of the counter and recovering any coolant present in that unit. The existing integral basin (not shown) may then be separated from the existing refrigeration unit by severing 102 the coolant lines (not shown) of the unit at a predetermined location. Thereafter, the integral basin may be excised from the counter by cutting 104 the basin away substantially along its perimeter and then lifting 106 the basin out of the counter. After removal of the integral basin, the replacement basin 10 may be positioned 108 in the cutout formed by the removal of the prior basin such that the basin support flanges 58 of the end walls and the lip 30 of the front wall 26 of the first frame 12 engage the countertop. The replacement basin 10 may then be further secured 110 to the counter by welding, commercial adhesives, fasteners, or the like. Finally, the conduit lines 16 of the replacement basin 10 may then be connected 112 to the coolant lines of the integral refrigeration unit using welding, fasteners (e.g., quick connect fasteners positioned on the ends of the conduit lines 16 of the basin 10), or similar connection means known in the art. It will also be appreciated that a similar procedure may be use to add one or more additional basins 10 to an existing counter that may or may not have a basin 10. However, in such instances, it may also be necessary to add one or more refrigeration units.
Having thus described my invention, various other embodiments will become known or apparent to those of skill in the art that do not depart from the scope of the invention as disclosed.
